Development of body image, eating disturbance, and general psychological functioning in adolescent females: a replication using covariance structure modeling in an Australian sample.

OBJECTIVE: The current study is a follow up to a covariance structure modeling (CSM) investigation of predictors of body image, eating dysfunction, and general psychological functioning in U.S. adolescent females. METHOD: Four hundred and seventy Australian girls (13-17 years old) completed measures of teasing history, body dissatisfaction, global psychological functioning, dietary restraint, and bulimic behaviors. They were also measured in order to compute body mass index (BMI). CSM techniques were used to analyze the relationships between these latent variables. Two a priori models were tested, one was selected, and post-hoc model-fitting was undertaken. RESULTS: The final model indicated that BMI directly influenced teasing, which directly influenced body dissatisfaction. Body dissatisfaction influenced both global psychological functioning and restriction, whereas restriction had a direct influence on bulimia. Global psychological functioning also had a direct influence on bulimia. DISCUSSION: The results support previous research indicating that teasing and body dissatisfaction are risk factors for the development of eating disturbances.

Weak electromagnetic fields improve body image perception in patients with multiple sclerosis.

Neuropsychological studies have demonstrated that multiple sclerosis (MS) is associated with various cognitive deficits and it has been suggested that it be considered a form of subcortical dementia. It is now recognized that visuoperceptive and visuomotor deficits commonly occur in MS patients particularly in those with chronic progressive course of the disease. The Human Figure Drawing Test has been employed in the assessment of generalized intellectual deterioration and specifically in the evaluation of visuoperceptive, visuospatial and visuoconstructional abilities in brain injured patients. I have demonstrated recently, on the basis of various drawing test, the external application of electromagnetic fields (EMFs) in the picotesla (pT) range intensity improved visuoperceptive and visuospatial functions in patients with MS. In the present communication I present five MS patients who were administered the Human Figure Drawing Test before and after a series of treatments with EMFs. Prior to application of EMFs four of these patients' drawings showed distortions, poor perspectives, impoverished facial expression, and lack of attention to details suggesting poor body image perception related to right posterior hemispheric dysfunction. In response to the administration of EMFs the group demonstrated improvement in motor disability which was associated with a striking improvement in the drawing particularly the drawings of the face the perception of which is localized to the right parietal lobe. These findings demonstrate that treatment with pT EMFs improves body image perception in MS patients thus corroborating previous observations which demonstrated this treatment modality to exert beneficial effects on cognitive functions in patients with MS.

Improvement of body image perception in Parkinson's disease by treatment with weak electromagnetic fields.

Neuropsychological studies have demonstrated that Parkinson's disease (PD) is associated with various cognitive deficits ultimately leading in about 30% of patients to the development of dementia. These studies have demonstrated also a greater decrement of right hemispheric functions which are manifested by visuospatial deficits occurring in up to 90% of PD patients. The Human Figure Drawing Test has been employed in the assessment of generalized intellectual deterioration and specifically in the evaluation of visuperceptive, visuospatial and visuoconstructional abilities in brain injured patients. I have demonstrated recently, on the basis of various drawing tests, that external application of electromagnetic fields (EMFs) in the picotesla (pT) range intensity improved visuoperceptive and visuospatial functions in Parkinsonian patients. In the present communication I present 4 fully medicated nondemented Parkinsonian patients who were administered the Human Figure Drawing Test before and after a series of treatments with EMFs. The Human Figure Drawing Test was selected for the study specifically since it was shown to be sensitive to the effects of surgery to the basal ganglia in Parkinsonian patients. Prior to application of EMFs these patients' drawings showed distortion, poor perspective, impoverished facial expression, and lack of attention to details suggested poor body image perception related to right posterior hemispheric dysfunction. In response to the administration of EMFs the group demonstrated a striking improvement in the drawings particularly the depiction of the face the perception of which is localized to the right parietal lobe. These findings demonstrate that treatment with pT EMFs improves body image perception in Parkinsonian patients, a deficit which may remain unaffected by treatment with standard dopaminergic pharmacotherapy.

Weight concern, body image, and abnormal eating in college women tennis players and their coaches.

In order to study weight concerns and eating disorders in women tennis players, 107 women tennis players and 26 women's tennis coaches from colleges across the U.S. responded to questionnaires relating to weight concern, body image, and abnormal eating. When evaluating drawings of female figures, players and coaches both considered the ideal body shape to be smaller than the healthiest one. Most players had normal weight, eating habits, and self-esteem; however, they also exhibited noticeable concern about their weight and appearance. Coaches revealed only moderate knowledge of weight related issues, believed such knowledge to be important, recognized that most of their players were of normal weight, and revealed somewhat negative feelings about overweight people. Players and coaches shared a healthy attitude toward tennis. The results of this study do not imply that college women tennis players are at greater risk of eating disorders than other young women, nor that college coaches are encouraging abnormal eating behaviors

Correlates of body image dissatisfaction in treatment-seeking men and women with binge eating disorder.

OBJECTIVE: We examined body image dissatisfaction (BID) in patients with binge eating disorder (BED). METHOD: Six predictors were considered in 343 consecutive treatment-seeking BED patients (76 men, 267 women): body mass index (BMI), age onset of overweight childhood teasing about weight or size childhood teasing about general appearance, depression, and self-esteem. RESULTS: Women reported higher BID than men. In women, depression, self-esteem, and childhood teasing about weight or size jointly accounted for 28.4% of the variance in BID. In men, depression, self-esteem, and BMI jointly accounted for 47.4% of the variance in BID. DISCUSSION: Findings highlight gender differences and the importance of adult psychological functioning (depression and self-esteem) for predicting BID in treatment-seeking men and women with BED.

Anthropometry, body composition and body image in dieting and non-dieting 8-16-year-old Swedish girls.

Anthropometry, body composition and body image were studied in 122 Swedish 8-16-y-old girls and their parents. The subjects participated in a 3-y prospective longitudinal study and were selected randomly after stratification for grades from those scoring in the upper vs. the lower thirds of the Children's Eating Attitudes Test (ChEAT) score distribution. The ChEAT was completed 6 mo before the present study together with a demographic and dieting questionnaire and a questionnaire for the estimation of body size. In total 43% (n = 52) admitted ever dieting ("Dieters") and 25% (n = 30) admitted that they were currently trying to lose weight. The anthropometric and body composition data indicated that ChEAT High-scorers and Dieters were somewhat fatter than Low-scorers and Non-dieters, although this pattern was not shown among the 8-y-olds or the 14-y-olds (High-scorers). The mothers of the ChEAT High-scorers were found to be somewhat fatter than the other mothers. A current vs. ideal body shape discrepancy was shown for both High-scorers and Dieters, with a larger discrepancy for the Dieters. All groups believed that their parents were aspiring for a leaner body.

Psychiatric aspects of head and neck surgery. Part II: Body image and psychiatric intervention.

Surgery of the head and neck leads to profound changes of body image, including disfigurement and difficulties with verbalization. The psychologic importance of alterations in these areas will be discussed as well as their effect on the conduct of psychiatric treatment. Psychiatric intervention in this population demands an active approach and special preparation for the therapeutic encounter is necessary.

Body image and physical disability--personal perspectives.

The current study used qualitative methodology to investigate the body image concerns of people with physical disabilities. Three males and four females aged between 22 and 50 years, in Melbourne, Australia, participated in the study. Three participants were heterosexual, two were homosexual and two described their sexual identity as predominantly heterosexual but 'bicurious'. The data were gathered through individual interviews of approximately 2 h duration, where participants responded to a set of predetermined open-ended questions. The study found that bodily impairment had a negative influence on the participants' psychological experiences, feelings and attitudes toward their own bodies. The impact of feedback from the social environment was highlighted, and there was evidence suggesting that individuals gradually adjust to their different bodies and increasingly accept their disabilities over time.

Sex differences in exercise motivation and body-image satisfaction among college students.

The current study was an expansion of one by Cash, Novy, and Grant in 1994, in which responses of 101 female nursing students were examined for associations between reasons for exercise, frequency of exercise, and body-image satisfaction. In the current study, 78 male and 100 female undergraduates between the ages of 18 and 25 years (M = 21.2, SD = 1.9) from various majors completed a demographics/frequency of exercise survey, two body-assessment inventories, and the Reasons for Exercise Inventory of Silberstein, Striegel-Moore, Timko, and Rodin. Contrary to Cash, et al.'s findings, only health and fitness reasons were predictive of women's frequency of exercise, and women's dissatisfaction with specific bodily attributes was not significantly related to any reasons for exercising; however, like women in their sample, the current students who experienced more situational body dissatisfaction exercised for appearance and weight control. Sex comparisons indicated similar dissatisfaction with specific bodily attributes among men and women, but values were not significantly associated with any reasons for exercising. Women reported higher situational body dissatisfaction and exercising for appearance-related reasons more than men. Current participants may represent a more diverse group than previously tested, and the inventory's factor structure may not be generalizable to men and women.

Reducing loss of image quality because of the attenuation artifact in uncorrected PET whole-body images.

UNLABELLED: In whole-body PET, it is not unusual to shorten the study time by omitting the transmission scan and to ignore attenuation during reconstruction. If a transmission scan is available, many centers reconstruct the images with, but also without, attenuation correction. Although ignoring attenuation leads to an artifact in the reconstructed images, these images still provide valuable diagnostic information in oncologic applications. Several authors have reported that the attenuation artifact may actually increase the tumor-to-background ratio. In this study, we analyzed the causes of the artifact and proposed a new algorithm to reduce the adverse effects on visual image quality. METHODS: We analyzed the causes of the attenuation artifact mathematically and numerically, and we examined its effect on tumor-to-background ratio and on signal-to-noise ratio. In addition, we showed that the attenuation artifact may lead to loss of image detail in conventional maximum-likelihood expectation maximization (MLEM) reconstruction. A new maximum-likelihood algorithm allowing negative reconstruction values (NEG-ML) was derived to reduce this loss. RESULTS: The attenuation artifact consists of 2 components. The first component is the well-known scaling effect: The apparent activity is reduced because attenuation decreases the fraction of detected photons. The second component is a relatively smooth negative contribution that is added to attenuated regions surrounded by activity. The second component tends to increase the tumor-to-background ratio. However, a simulation experiment shows that this increase in signal may be entirely offset by an increase in noise. The negative contribution can interfere with the nonnegativity constraint of the MLEM algorithm, leading to loss of image detail in regions of high attenuation. The new NEG-ML algorithm avoids the problem by allowing negative pixel values. The algorithm is similar to MLEM in the suppression of the streak artifact but provides more anatomic information. In our department, it is in routine clinical use for reconstruction of PET whole-body images without attenuation correction. CONCLUSION: Ignoring attenuation may increase the tumor-to-background ratio, but this increase does not imply improved tumor detection. The NEG-ML algorithm reduces the adverse effect of the attenuation artifact on visual image quality.

The body image in health and disease: exploring patients' maps of body and self.

Patient education in chronic diseases should always take into account the many maps--individual, cultural and medical--that patients have of their own bodies, in both health and disease. Physicians should become explorers, working in co-operation with patients and their families to understand their perceptions of body and self--and whether or not these are compatible with medical interventions.
